Rogue Audio Cronus 12AU7-12AX7 tubes choices


I own a Rogue Audio Cronus amplifier since two weeks and I want to upgrade the preamplifier section tubes which are 12AX7 and 12AU7.

First, I'm wondering the fonction of each tube. I don't want to replace the one for the phono section if it is so because I don't use this phono. What are the fonctions of each preamplifier tubes on the Cronus?

Second, I'm looking for a musical, engaging and well balance sound. What are your tubes suggestions?

Sebastien1,

I know this is off topic, but I've seen your postings on Audiogon and HUG in relation to the Harbeth SHL5. I don't know if you are still using that speaker, but it's one I've been most interested in. Are you using the Cronus with the SHL5? I saw that you had some experience with the Luxman integrateds. I believe you had the 505u, and one of the Class A amps, and was wondering why you chose to go the Cronus route after hearing the Luxmans. I've been interested in the Cronus, and have heard the Magnum version at a local dealer , but was hoping to hear your experiences with various Luxmans and Rogues with the Harbeth. I haven't had a chance to start auditioning amps yet, but would appreciate anything you could share about your experiences. I was also wondering if you had any thoughts on the strengths of the Cronus relative to the Magnum version and Luxman integrateds. Any of your thoughts on these questions would be appreciated. I’d be willing to spend the extra money on the one of the Luxmans or the Magnum version of the Rogue if it were worthwhile, but would prefer to save the extra money for music, so it’d be great to hear someone who has heard the Rogue/Harbeth combination after having heard the other combinations. So far, I have the usual suspects of LFD and Luxman on my audition list, based on reviews and forums, but there hasn’t been much about the Cronus/Harbeth combination, aside from a brief mention in Stereophile re: Son Ideal at the Montréal show last year.

Thanks in advance for your time!
